In view of eco-benign nature of nanoparticles prepared via green routes, in the present investigation, silver, zinc oxide and titanium nanoparticles have been prepared using onion (Allium cepa) extract, which act a reducing and capping agent. The prepared nanoparticles were characterized using UV-visible, FT-IR, XRD, AFM, and SEM techniques. The nanoparticles efficacy was studied as antibacterial agent by applying on cotton fiber. Cotton nanofiber was coated by soaking in solutions of nanoparticles (Ag, ZnO and TiO2) and their biological efficiency was evaluated and it was observed that the cotton fiber soaked with nanoparticles showed a strong biological efficiency against panel of selected strains. This coated nanofiber of cotton shows a mat with high surface area versus uncoated fiber. Results revealed that green synthesized nanoparticles enhanced the antibacterial activity of cotton fiber, which have potential applications in textile industry.
